Philip Langdale 5186651f30 vo_gpu: hwdec: load hwdec interops on-demand by default
Historically, we have treated hwdec interop loading as a completely
separate step from loading the hwdecs themselves. Some hwdecs need an
interop, and some don't, and users generally configure the exact
hwdec they want, so interops that aren't relevant for that hwdec
shouldn't be loaded to save time and avoid warning/error spam.

The basic approach here is to recognise that interops are tied to
hwdecs by imgfmt. The hwdec outputs some format, and an interop is
needed to get that format to the vo without read back.

So, when we try to load an hwdec, instead of just blindly loading all
interops as we do today, let's pass the imgfmt in and only load
interops that work for that format. If more than one interop is
available for the format, the existing logic (whatever it is) will
continue to be used to pick one.

We also have one callsite in filters where we seem to pre-emptively
load all the interops. It's probably possible to trace down a specific
format but for now I'm just letting it keep loading all of them; it's
no worse than before.

You may notice there is no documentation update - and that's because
the current docs say that when the interop mode is `auto`, the interop
is loaded on demand. So reality now reflects the docs. How nice.

mpv

Overview

mpv is a free (as in freedom) media player for the command line. It supports a wide variety of media file formats, audio and video codecs, and subtitle types.

There is a FAQ.

Releases can be found on the release list.

System requirements

  • A not too ancient Linux, Windows 7 or later, or OSX 10.8 or later.
  • A somewhat capable CPU. Hardware decoding might help if the CPU is too slow to decode video in realtime, but must be explicitly enabled with the --hwdec option.
  • A not too crappy GPU. mpv's focus is not on power-efficient playback on embedded or integrated GPUs (for example, hardware decoding is not even enabled by default). Low power GPUs may cause issues like tearing, stutter, etc. The main video output uses shaders for video rendering and scaling, rather than GPU fixed function hardware. On Windows, you might want to make sure the graphics drivers are current. In some cases, ancient fallback video output methods can help (such as --vo=xv on Linux), but this use is not recommended or supported.

Downloads

For semi-official builds and third-party packages please see mpv.io/installation.

Changelog

There is no complete changelog; however, changes to the player core interface are listed in the interface changelog.

Changes to the C API are documented in the client API changelog.

The release list has a summary of most of the important changes on every release.

Changes to the default key bindings are indicated in restore-old-bindings.conf.

Compilation

Compiling with full features requires development files for several external libraries. One of the two build systems supported by mpv is required: meson or waf. Meson can be obtained from your distro or PyPI. Waf can be downloaded by using the ./bootstrap.py script. It will get the lastest version of waf that was tested with mpv. Some documentation about the differences between the build systems are located in build-system-differences.

Meson

After creating your build directory (e.g. meson build), you can view a list of all the build options via meson configure build. You could also just simply look at the meson_options.txt file. Logs are stored in meson-logs within your build directory.

Example:

meson build
meson compile -C build
meson install -C build

Waf

For a list of the available build options use ./waf configure --help. If you think you have support for some feature installed but configure fails to detect it, the file build/config.log may contain information about the reasons for the failure.

NOTE: To avoid cluttering the output with unreadable spam, --help only shows one of the two switches for each option. If the option is autodetected or enabled by default, the --disable-*** switch is printed; if the option is disabled by default, the --enable-*** switch is printed. Either way, you can use --enable-*** or --disable-** regardless of what is printed by --help.

To build the software you can use ./waf build: the result of the compilation will be located in build/mpv. You can use ./waf install to install mpv to the prefix after it is compiled.

Example:

./bootstrap.py
./waf configure
./waf
./waf install

Essential dependencies (incomplete list):

  • gcc or clang
  • X development headers (xlib, xrandr, xext, xscrnsaver, xinerama, libvdpau, libGL, GLX, EGL, xv, ...)
  • Audio output development headers (libasound/ALSA, pulseaudio)
  • FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample)
  • zlib
  • iconv (normally provided by the system libc)
  • libass (OSD, OSC, text subtitles)
  • Lua (optional, required for the OSC pseudo-GUI and youtube-dl integration)
  • libjpeg (optional, used for screenshots only)
  • uchardet (optional, for subtitle charset detection)
  • nvdec and vaapi libraries for hardware decoding on Linux (optional)

Libass dependencies (when building libass):

  • gcc or clang, yasm on x86 and x86_64
  • fribidi, freetype, fontconfig development headers (for libass)
  • harfbuzz (required for correct rendering of combining characters, particularly for correct rendering of non-English text on OSX, and Arabic/Indic scripts on any platform)

FFmpeg dependencies (when building FFmpeg):

  • gcc or clang, yasm on x86 and x86_64
  • OpenSSL or GnuTLS (have to be explicitly enabled when compiling FFmpeg)
  • libx264/libmp3lame/libfdk-aac if you want to use encoding (have to be explicitly enabled when compiling FFmpeg)
  • For native DASH playback, FFmpeg needs to be built with --enable-libxml2 (although there are security implications, and DASH support has lots of bugs).
  • AV1 decoding support requires dav1d.
  • For good nvidia support on Linux, make sure nv-codec-headers is installed and can be found by configure.

Most of the above libraries are available in suitable versions on normal Linux distributions. For ease of compiling the latest git master of everything, you may wish to use the separately available build wrapper (mpv-build) which first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.

If you want to build a Windows binary, you either have to use MSYS2 and MinGW, or cross-compile from Linux with MinGW. See Windows compilation.

Release cycle

Every other month, an arbitrary git snapshot is made, and is assigned a 0.X.0 version number. No further maintenance is done.

The goal of releases is to make Linux distributions happy. Linux distributions are also expected to apply their own patches in case of bugs and security issues.

Releases other than the latest release are unsupported and unmaintained.

See the release policy document for more information.

Bug reports

Please use the issue tracker provided by GitHub to send us bug reports or feature requests. Follow the template's instructions or the issue will likely be ignored or closed as invalid.

Using the bug tracker as place for simple questions is fine but IRC is recommended (see Contact below).

Contributing

Please read contribute.md.

For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on.

You can check the wiki or the issue tracker for ideas on what you could contribute with.

License

GPLv2 "or later" by default, LGPLv2.1 "or later" with --enable-lgpl. See details.

History

This software is based on the MPlayer project. Before mpv existed as a project, the code base was briefly developed under the mplayer2 project. For details, see the FAQ.
